The Tri-Ergon sound-on-film system was developed from around by three German inventors, Josef Engl — , Joseph Massolle — , and Hans Vogt — The Tri-Ergon process involved recording sound onto film using the "variable density" method, used by Movietone and Lee De Forest's Phonofilm, rather than the "variable area" method later used by RCA Photophone.

Zu Audio , a small company based in Ogden, Utah, represents to me the absolute modern American success story. I love everything about it: the quest for audio perfection, the pursuit of a dream of doing something differently, and that their products are produced by caring artisans right here in the good old USA. Indeed, Zu is evidence that those with a unique idea and enough gumption can still succeed and realize their dreams right here and right now. While initiating what was probably my own second or third vinyl renaissance, I realized that my ancient Michell Gyrodec turntable needed a new cartridge installed on its crazy-heavy Fidelity Research tonearm.

Electrostatic disinfecting is a way of quickly and evenly coating a surface with a disinfecting solution. The Check Mate Electrostatic Cleaning System provides rapid, uniform application of fast-acting chemicals to allow for exceptional coverage in a fraction of the time - using chemicals that boast kill times up to 10 times faster than competitive products. Search Just apply an electrical "push" in the form of electrostatic repulsion, then the silicon becomes insulating, so large currents can be switched on and off. Electrostatic induction was used in the past to build high-voltage generators known as influence machines. Simco-Ion's comprehensive product line incorporates years of research, engineering, and field experience.

Electrostatic Tus Hais Zoo

Marc Milecofsky was born on in Lakewood, New Jersey. For those of you who do not know who he is maybe you know him better by Marc Ecko. In The company recorded over 1 billion dollars in gross profit. In the San Diego Zoo even named a baby rhino after the designer. He also purchased two white rhinos in which saved them from being purchased by canned hunt operators out of Texas.

This was going to be the year when the four-channel business would finally be cleared up, everybody would know what was best to buy, and audio would boom again if that expression is permissible. If anything, the industry is a step further from agreement than it was a year ago, for the Sansui QS system has become an even more ponderable rival to the CBS SQ system on the matrix side of the dispute, while the RCA CD-4 discrete system has produced an increasingly improved product. Increasing numbers of amplifier makers offer all three four-channel choices. For the benefit of those who have come in late, four-channel audio is an attempt to present in the living room four separate and equal perspectives on a single piece of sound.
